I have almost the exact same grill. Mine was a "special edition" which meant mica green lid, two flip tables, SS flav bars (still going strong after 20+ years) and stamped SS grates.
I swapped the stamped SS grates out for the PCCI 10+ years ago. I like those a lot -- more (personal preference) than SS rods. Among other reasons, I prefer to have black grates -- so the Mrs. does not bother me to keep scrubbing the SS grates to make them look shiny.
And then a few years ago I got (I know I know) a set of GrillGrates. They are awesome imo. I use the flat side primarily -- gives me greatly improved searing capability and are also handy for shrimp, veggies, smash burgers and other griddle type cooks. Reduces flare ups.
My standard set up is one side PCCI and the other side flat GGs. But depending on the cook, I will sometimes do all PCCI, all GG flat, or all GG rails. Works very well for me.
